To all whom it may concern: The to plate B is provided'with en an'ni- Beit known that l, JOHN M.

Fig. 4 is an enlargei'i detail plan nular portion d! fitting snugly against and view with the rotary closing plaie removed embracing the raised annular portion b1 of and with the pivot lips on the iop plate upthe top plate B, and it is also rovided with 5 turned ready lor receiving the closing plate; a depressed center (Z2 fitting ilat y against and 90 Fig. 5 isa detail plan vieu-'of the rotary eloscorresponding to the depressed Center vof ing plate, and Fig. (i is a detail sei-tion on line the top plate B. The rotary closing plate D 6;6 of Fig. 5. is provided preferably with twelve discharge In the drawing, A represei'ils the body of a openings or porlorations d3 arranged in two 40 can or box and B is the perforated top plat-ev circular rows of six holes in ezioli row and'95 permanently and irreniovably seained lo the with the holes or perforations` i-n the inner body A by a. folded or other seani l). row staggered in respect to those in the outer C is the bottoni head of the een, which is row. 'lhe central pivot slot or opening d in permanently and irreinovably secured to the the rotary closing plate D is provided With ower end ol' the body .i by a folded or other stop edges or margins d adapted to engage 100 seam o after the van or box has been Ylilli d the pivot tongues b4 on the top plete B and with iowder. As both. the bottonihrad limit the rotary or turning niovenient ofthe and t e perforated top B are pernianenily closing plate l) in both directions, these stop and irreniovably seauied with the bodyv A ol edges Ior niargins being cooperative] f ar- 0 the. can, my sifter lop van is thus niade nonranged in respect to the perforations da in the -105 reiillable, because alter the contents have closing plate, so that when the closing plate been used onee, tlioean eannot be praetieally is turned to its lilnit in one direction, the perrellled with spurious goods through the foi'ations'd" in the closing lato D will regissn'iall disrharge openings or pei'loratimis in ter with eorieswmling hoes or perforations 5 the si'liei top B. b3 in the top p ate B; and so that when the 110 rotary closing plate is turned to its limit in the other direction7 the discharge holes or perforations in the two plates will be out otl register with each other or in their closed posit-ion. The centralipivot slot or opening il in the closing plate l) may be made ol' any forni suitable for cooperation with the clenching' pivot tongues b4 in rotatably securing the two plates together and :serving asa stop to limit the turning movement oi the closing plate to cause the two plates to register' in their open and closed positions, but l prefer to make this pivot slot ol a substantially square or rectangular torni as shown in the drawing, with two curved sides tl.

As in my invention, the interengaging stops do not in operation slip past eachother, the stops produce no tendency to spring the plates apart, and I ain thus enabled to sccure a snug or close lit between the rotary Closing plate and the top plate and produce a sitter top powder box which is substaiitially tight against leakage olI powder. 'l`lie depressedcenters ot the two plates l l) and the annular raised portions ol the two plates cooperate with the pivot tongues and pivot slot in rotatably securing the two plates together and in causing one to l'reely and properly turn in respect to the other, and in securing a snug and powder tight lit ol' th(` two plates together; the depressed centers and raised annular portions also serving to stillen and strengthen the'plates and thus diminish the liability ol' their being separated or sprung apart at any portion oll their circumference so as to occasion leakage oll powder. [n order to provide the rotary closing plate with tinge-r pieces l'or turning it, which will not interfere with the snug close powder tight lit of the two` plates together and the proper cooperation ol the other parts, l l'urnish it with integral marginal lips d which are upwardly coiled into cylindrical linger pieces (Z7 so that the lingei' pieces have no tendency to separate the closing plate l'rom the to 'plate B at the circular margin or edge O the closing plate, and by which the integral lip linger pieces are adapted to be readily engaged by the linger-or thumb in turning the rotary closing plate and also given a smooth linish and a strong rigid form.

In practice I prefer to make the pivot slot, or opening in the rotary closing plate substantially square, and the space between thc two pivot tongues b4. on the top plate l substantially equal to the width ol the pivot tongues so that the two pivot tongues will present a substantially square pivot l'or engagenient with the.substantially square hole in the rotary closing plate, and. with the play between the pivot tongues and the. stop edges or margins ol' the pivotrv hole such as to permit the requisite rotatioir oll the closing plate and the proper stopping thereol in its open and closed positions in whatever position the two plates may be turned in. respect to each other in assembling them. This is a great convenience in assembling or putting the plates together and also prevents the rotary closing plate being applied to the top plate in such way as to be incapable of cooperation therewith. ln assembling the plates, l have preferred to turn the rotary closing plate with the straight side (lx olI its pivot opening` r/ parallel to the base ol the pivot' tongues l1". By arranging the discharge openingsl in two circular rows with six holes in each row, the holes in one row staggered in respect to the holes in the other, the rotai'y closing plate niay be turned in any possible position in respect to the top plate in assembling the two plates and still the stop devices on the two plates will properly engage each other and cause the plates to properly register in open and closed position.

'lhe pivot lips or tongues i'i are somewhat less in width than the straight sides d in the pivot opening t/ oll the rotary closing plate l), so that the closing plate can turn in one direction sulliciently to bring the pcrl'orations li d"i into registry with Aeach other, and in the opposite direction sulliciently to bring such perl'orations out ol' registry with each other.
